1, pruning. For tomato varieties with infinite growth, single stem pruning and head-changing pruning should be adopted. (1) Single stem and pruning. Leave only one trunk, remove all the side branches and leave fruit on the trunk. According to the different stubble and cultivation methods, 4- 10 ear fruit is generally selected, but the number of ears and fruits reserved for overwintering flowers is appropriately increased. (2) change the head and trim. The trunk leaves 2 true leaves before the 3rd ear for topping, one in the middle to replace the trunk growth after fruit setting, and 3 ears on this branch for topping, so the head is changed for 2-3 times.

2. Fight. Tomato lateral buds have strong germination ability and often grow multiple lateral branches at the same time. In order to promote the growth of roots and the branching of trees, the initial branching time can be delayed to about 5 cm, and then smoothed in time when the branching length is 1-3 cm. Branching is generally combined with rattan, which should be carried out in sunny morning, when the wound heals quickly and reduces disease infection. Pay attention to healthy strains first, and then pay attention to sick strains. Tomato planting should pay attention to these five management points if you want high yield and high quantity!

3. Choose your heart. When the ear on the main branch grows to a certain number, leaving two real leaves above the ear is called topping. After core removal, the growth point stops growing, which can concentrate nutrients made by leaves to supply fruit growth and promote fruit growth and maturity. When topping tomato plants, don't pinch off all the tops, leave 2-3 leaves, and make nutrients for the growth of lower flowers and fruits through photosynthesis, which can also play a certain role in shading and prevent the upper fruits from being burned by the sun. Note that coring should also be carried out on sunny days. In addition, tomatoes with limited growth types have the characteristics of self-capping and do not need artificial enucleation.

4. Raise flowers and fruits. Under the influence of environmental factors such as low temperature, high humidity and insufficient light, winter tomato is prone to poor flowering, poor pollination and fertilization, resulting in low fruit setting rate and even falling flowers and fruits. In order to improve tomato yield, especially in the early stage, farmers are advised to use tomato essence or 2,4-D to treat flowering tomatoes in time. (1) If tomatoes are used: When there are 2-3 flowers in the 1 inflorescence of tomatoes, 20-30mg/L tomatoes can be sprayed to promote fruit expansion. (2) If 2,4-D is used, when the tomato blooms, brush the pedicel with 2,4-D liquid of 15-20mg/L, and be careful not to let the liquid get on the pedicel to avoid phytotoxicity.

5. Sparse flowers and fruits. Before the inflorescence is treated with tomato essence or 2,4-D, if it is found that there are too many flowers per panicle, it is necessary to remove abnormal flowers and redundant florets first, and generally leave 4-5 flowers per panicle.
